Interesting about the balsam fir.
I did extensive hiking around Long Island after sandy and determined that species acted different then expected. Oaks received by far the most damage. They tended to fully uproot. I was able to locate several full blow downs in a preserve near my house. 100 mature red and white oaks toppled like dominos. Meanwhile red maple, sweet gum, black gum and tulip right next to them where perfectly fine.
My theory on why the oaks took such a comparable beating is due to their folliage. Oak leaves are very robust and thus tended to stay on the tree during the many hours of strong winds leading up to the period of extreme winds that caused the blow downs. Most of the other species had a good amount of their folliage stripped earlier in the storm.
